    Reintroduction of the Archaic Variant of NOVA1 in Cortical Organoids Alters Neurodevelopment

    To investigate the functional importance of an amino acid change in humans, investigators reintroduced the archaic allele into human iPSCs using genome editing and then followed their neural development through cortical organoids.

    Human Neurons from Christianson Syndrome iPSCs Reveal Mutation-Specific Responses to Rescue Strategies

    To hasten treatment development, researchers established iPSC lines from patients with Christianson syndrome representing a mutational spectrum, as well as biologically related and isogenic control lines.

    Abstract

    Neurodevelopmental Defects and Neurodegenerative Phenotypes in Human Brain Organoids Carrying Parkinson’s Disease-Linked DNAJC6 Mutations

    To study the roles of DNAJC6 in Parkinson’s disease (PD) pathogenesis, scientists used human ESCs with CRISPR-Cas9-mediated gene editing. They showed that DNAJC6 mutations caused key PD pathologic features, i.e., midbrain-type dopamine neuron degeneration, pathologic α-synuclein aggregation, increase of intrinsic neuronal firing frequency, and mitochondrial and lysosomal dysfunctions in human midbrain-like organoid.

    Production and Cryopreservation of Definitive Endoderm from Human Pluripotent Stem Cells under Defined and Scalable Culture Conditions

    The authors provided a detailed protocol for mass production of definitive endoderm from human PSCs in scalable and easy-to-handle suspension culture using a rotating Erlenmeyer flask or a sophisticated, fully controllable, 150ml stirred tank bioreactor.

    Abstract

    Simple and Reliable Detection of CRISPR-Induced On-Target Effects by qgPCR and SNP Genotyping

    Scientists describe a broadly applicable framework for detecting on-target effects in genome-edited iPSC cells and organisms after non-homologous end joining-mediated and homology-directed repair-mediated editing.

    Abstract

    Functional Patient-Derived Cellular Models for Neuropsychiatric Drug Discovery

    Researchers discuss a novel strategy for neuropsychiatric drug discovery which aims to address limitations by identifying disease-related functional responses in a variety of patient-derived cells, such as iPSC-derived neurons and organoids or peripheral blood mononuclear cells.

    Pluripotency and Immunomodulatory Signatures of Canine Induced Pluripotent Stem Cell-Derived Mesenchymal Stromal Cells Are Similar to Harvested Mesenchymal Stromal Cells

    With a view towards harnessing the therapeutic potential of canine mesenchymal stromal cells (cMSCs) as modulators of inflammation and the immune response, and to avoid the issues of the variable quality and quantity of harvested cMSCs, scientists examined the immunomodulatory properties of cMSCs derived from canine iPSCs, and compared them to cMSCs harvested from adipose tissue and bone marrow.
